Sentai's my favorite of the franchises, but mecha has always been one of my least favorite aspects. The only time I can tolerate mecha is in the Bioman through Jetman run, because they only devote a mercifully brief 87 seconds for the mecha fight. :laugh: Those shows realized there's more important things to focus on than the mecha, whereas the new shows think the mecha matters above all else.
But around Megaranger, the mecha scenes started getting longer. Gaoranger's the first one I noticed where they'd devote, like, five minutes to a mecha scene. Hurricanger, for one, seemed like it had entire episodes consumed with mecha fights!
I don't understand the appeal of giant battles, really. From kaijuu flicks to Ultraman to mecha. When it comes to sentai's mecha scenes, I find those fights to be impersonal. I think the original idea was the ultimate representation of the five heroes uniting as one, but they already accomplish that in the big fight that takes place -- human scale -- on the ground.
